What Are All-on-4 Dental Implants?

More than 35 million Americans have lost all of their teeth, and 178 million are missing at least one tooth, according to studies conducted by the University of Wisconsin School of Medicine and Public Health.

Your smile is one of the first features people notice about you. This means that these individuals can experience issues that not only affect their speech and chewing abilities, but also their self- esteem and the way they present themselves to the world.

If you are missing one or more teeth, all-on-4 dental implants may be the right choice for you!

Why All-On-4 Implants Were Created

Typically, patients who are missing teeth have moderate to advanced bone loss in either the upper jaw, lower jaw, or both. Oftentimes, dentists treat them with conventional dentures because they are unable to receive fixed bridges or even removable implant-supported prosthesis. It can be difficult for dentists to place implants in these areas due to inadequate bone structure, jaw nerve positions, and other anatomical challenges.

The difficulties that clinicians have faced when working with bridges and prosthesis inspired them to create better surgical and clinical techniques. This is how all-on-4® or all-on-6 dental implants, otherwise known as hybrid dentures, were born.

How Do All-On-4 Dental Implants Work?

All-on-4 Dental Implants

Hybrid dentures are also called all-on-6 or, more commonly, all-on-4 dental implants, because they allow for the placement of four to six implants per arch. Two implants are placed vertically in the anterior region, or the front of the mouth, and two are placed at an angle in the posterior, or the back of the mouth.

Through this technique, dental specialists are able to maximize the uses of the existing bone structure and encourage bone regeneration. The patient is also free from the need for difficult procedures like nerve repositioning and bone grafts.

What are the Benefits of All-On-4 Dental Implants?

Easy to clean

Although all-on-4 implants are not susceptible to tooth decay in the same way your natural bone structures are, it is still important to take care of them because they can develop plaque. Fortunately, the maintenance process is fairly simple and is similar to the way you cleaned your natural teeth. If you choose dental implants, you might do well with a low-abrasive, tartar-control toothpaste. You might have a slightly more difficult time flossing, but floss threaders easily solve this issue. You should be careful not to use your implants for activities outside of chewing food and speaking, like opening bags or bottles and biting your nails.

Immediate function

One of the best parts of all-on-4 implants for many patients is that they are able to enjoy and use their smile immediately. This is because the implants bond with the jawbone right away, creating stability. Most patients can return to their normal activities within a few days, but they should be careful to avoid heavy manual labor, excessive talking, and eating hard foods for 3-4 days after the procedure.

Improved bio-mechanics

Bio-mechanics, which refer to the connection between the implant and bone, play an important role in the success of all-on-4 implants. This is because once implants are attached, they do not move. The improved bio-mechanics of all-on-4 implants allow for optimal implant-to-bone contact.

Less need for bone grafts

During a bone graft procedure, the surgeon places a new piece of bone in the area where the bone needs to heal. Most patients who receive all-on-4 implants do not require this. While bone grafts are still a common procedure, they are often unnecessary for patients who receive all-on-4 implants because the implants utilize the areas where bone is denser.

Less complex surgery

All-on-4 implants are a minimally invasive treatment that allow patients to take home a new smile in just one day. Traditional implants require as many as 20 implants on the upper and lower arches. Patients often require bone grafting and sinus augmentation to replace the jawbone with traditional implants. As their name suggests, all-on-4 dental implants only utilize four separate implants, so even patients who have significant jawbone loss are often good candidates for the procedure.


When compared to alternatives like traditional implants, patients tend to find that all-on-4 implants are more affordable. With traditional implants, patients are responsible for the cost of potentially expensive prosthetics as well as the additional treatment time it takes to prepare them.

A well-documented success rate

Published studies have consistently shown a 98.2% success rate using all-on-4 implants. Patients appreciate the life-changing results and their ability to chew, speak, and smile with ease again. With proper care and healthy oral hygiene habits, patients can enjoy the benefits of all-on-4 dental implants for many years to come.
